Assessment of the Content of Plastic Inclusions in PET Food
AI summary Read the abstract
Researchers assessed microplastic contamination in commercial wet pet foods sold in pouch packaging from well-known brands, comparing them to a laboratory-prepared sample made without contact with polymeric materials. The study found microplastics in all commercial samples regardless of price point, while the laboratory control contained 2.3-4.4 times fewer microplastic particles, implicating packaging and processing as contamination sources.
Исследование выявило загрязнение микропластиком влажных кормов для животных в пауч-упаковках. Были изучены корма известных брендов и лабораторный образец, изготовленный без контакта с полимерами. Микропластик обнаружен во всех образцах независимо от стоимости, однако лабораторный образец содержал в 2.3-4.4 раза меньше микропластика. The study revealed microplastic contamination of wet animal feed in spider packages. Well-known brand feeds and a laboratory sample made without contact with polymers were studied. Microplastic was found in all samples, regardless of cost, but the laboratory sample contained 2.3- 4.4 times less microplastic.

Microplastic prevalence in commercially available petfoods
AI summary Read the abstract
Researchers tested 38 popular UK pet foods and found tiny plastic bits (microplastics) in most of them—76% of products had at least some contamination, with cheaper "value" brands testing worse than premium ones. A large dog eating wet food could swallow over 300 plastic particles a day, meaning our pets may be ingesting even more microplastic than we do, and their waste could be spreading this plastic pollution into soil and wildlife. While the direct health effects on pets aren't fully known yet, this is a good reminder that microplastic exposure is showing up in more places than we realized—including the food bowls of the animals we care
Microplastic Contamination in Pet Foods and Fish Meals: Implications Beyond Human Health
AI summary Read the abstract
Researchers examined microplastic contamination in pet foods and fish meals, finding that plastics from fisheries, aquaculture, and environmental pollution enter animal feed supply chains in ways that have consequences beyond human health, affecting companion animals and raising broader questions about food system safety.
Occurrence and characterization of microplastics in dry pet food: Investigating geographical variations between European and South American markets
AI summary Read the abstract
Dry pet food in Spain and Ecuador contains tiny plastic particles (microplastics), with loose, unpackaged food in Ecuador showing the highest contamination—likely picked up during bulk storage and handling. Dogs eating these foods may be swallowing hundreds of plastic particles daily, some small enough to potentially pass into body tissues, along with a hormone-disrupting chemical called BBP. While this study focused on pets, it's a reminder that packaging and food handling practices matter for microplastic exposure in general, a growing concern for human health too.
Manifestation of Microplastics in Cat Chow under Microscopic Examination
AI summary Read the abstract
Researchers examined 50 cat food samples from Thailand — 25 dry and 25 wet — using microscopy to detect the presence of synthetic microplastics in commercial cat chow, raising concerns about microplastic ingestion by pets and potential pathways of environmental plastic contamination through pet food consumption.
A plastic diet for pets: Exploratory evidence of microplastics in commercial dry pet food in Spain
AI summary Read the abstract
Researchers detected microplastics in all five commercial dry pet food brands tested in Spain, with dog food containing more than twice the particle count of cat food, and developed a risk index model suggesting dogs face greater systemic exposure risk while cats may be more prone to chronic intestinal inflammation from fiber-type particles — positioning pets as sentinels for household microplastic exposure.
